To alt whom it may conccmf Be it known that I-, J-USTUS G. Po'r'mrn; a citizenof the United States; and residing at Cypress Hills, Brooklyn, in the county of Queens and State of New York, have: itsvented certain new and useful-1m 'rovements in. Dumping-Cars, of which: the fo owing: is a specification, such fiswillzenabl th s Ski-fled PP S to make and fuse the same. y

, This invention relates to dumping cars for use .in' hauling or gravel; coal or any other material which it may be desired to-unload by dumping; and the object of the-inventionis to provide an' roved car of this class'designed: todum 1m its oad at the side or sides-thereof; and wit dumlping car showing both sides closed in full mes, and one side open in dotted lines, Fig. 2 a transverse seotions-howing one side of thecar closed and one side 0 en, Fig. 3 a partial: bottom plan view of a fa se or dumping. bottom with which my improved car is provided, Fig. 4 a section on the line 4, 4- of ig. 1, Fig. 5 a plan view of adetail of the construction shown in Fi 3, and ;'Fig. 6 a section on the line 6, 6 0 Fig. 3.

In the drawing forming part of cation I. have shown my invention applied to a car a supported by bolsters or other truck work I), but it will be understood that the latter forms no part of the invention. The car a is of the class in which the load is dumped at the sides instead of through the bottom thereof, and in practice the opposite sides of the car are composed of two l; aged parts or door members a and d, the doors 0 being hinged at the top of the car and extending when closed to the bottom thereof,

and the doors d being hinged at the bottom oi the car and extending only-part way up I when closed, and the doors d when closed .Speoiflcationofl Letters Patent. Application flledfiovomherrllil 1907. Serial No. 4021581 transporting. sand,.

tops of the doors (1, when; the latter are closed, are laced vertically arranged brackis; d inw ich are; mounted drums d? it 'ded with ratchets d", and overeach o the hets d ispivoted a gravity pawl d9 haning nosed adapted to operate in connectiori-\ th the corresponding ratchet d;

Co ected-with the drums d are'cordtro:

these on s or cables d? are.;connected* with .the doorembers d by pivot or link devices d Each end of the car is also provided above the brackets d with verticallaw= ran (1' brackets: e which are set inward l 'of the rackets-d and mjountedin thebrao ets care. drums e provided with ratchets ei aaul' pivoted oventhe ratchets e are gravity pawle e provided with a nose e, and the nosweiofi the gravity awl e operate in connection with the rate ets e brackets 'e and the sides of the car, as shown -with rollers f a apted to' bear onplates: j secured to the side door members a and'con nected with the lever are cords or'cables ji which are wound ont e drums a, said' cords or cables f being preferably made of'wire.

At the upper outer corners-of the endswof' the car are segmental or cunved f 5 which are secured at f", and these arms pass through the-shorter endsof the lever f, and between said ends of the lever fand theends of the a'rrnsf at f are placedspiralsplings= At the opposit'e'ends of the car, and' at e ets g, and passed longitudinallythrouglr the bottom portion of the car are parallel shafts, g and at each end of the car, the'shaftsg. are provided with drums g provided on their are provided at their faces with radial sockets or recesses 9 as olearl shownin Fig. 4.

ratchets (l are pawls' 9 having noses= which operate in connection with the ratchetsdgt; and said pawls are provided'with upwa y directed handles 9'', and at the outer sides of said pawls are placed-stop pins 9 in the form of construction shown. The shafts g are provided within the car with supports or bearings (L3, mounted on the bottom a of the car, and the car is also provided with false or sup plcmental inner bottorn'niein'bers h which extend longitudinally of the car, and which are pivoted or hinged at if centrally and cablesfll, preferably compesedoil wire, and

Pivoted between the top portionsofi the at e, arc'levers f rovided at their lowerends bottom thereof are placed horizontal brack Pivotcd to the en s of the car over the inner sides with ratchets g, and the drumsg.

longitudinall of the ear to the supports a, or to upward y directed extensions a, of said supports.

v e shafts g are provided at intervals with arms h which bear on thickened portions or members h, and secured to the bottom of said inner or false bottom members h are keepers k arrangedjn pairs parallel with the parts h and h.

The inner or false bottom members are proor false bottom members f are provided with pins '5 which pass putwardlythrough the inner slots i and the said inner or false bottommembers fare also provided with'pins i p which ass outwardly through the outer slots i, an connected with the pins i and with the pins '13 are spirals rings a which normally serve to force the slides i outwardl this construction being clearly shown in F 3 5and6. .r

Secured to the bottom'of the outer edge portion of the inner false or s pplemental ottom members h are plates t rough the mner'edge portions of which t e pins '5" are passed, and the slides 11 are mounted between the plates 7' and the outer ed e portionsof the inner false or supplemental ottom members h, and thesaid latesj are provided at intervals with thic ened blocks or bearings 7' 4 a which are adapted, in the lowest position of the parts h, to bear on the bottom a of the car as shown at the left in Fig. 2.

Ifach of the main or upper side door members c is provided, in the form of construction shown, and at any suitable oints with a supplemental door or doors hinged at k an provided with bottom fastening devices k. In Fig. 1 of the drawing the side door members 0' and d are both shown closed, and the cords ore-ables d and f are wound on the drums d and e, and with the parts in this position the car may be filled with any material through the top thereof, or it may be partially filled through the doors is, which latter may be closed and the filling process completedtln-ough the top of the car.

Suppose the inner false or supplemental bottom members It to be in the position shown'in full lines in Fig. 2 when the ear is filled. If now it is desired todump the car through the left hand side, all that is necessaryis to release thepawls d and e at said side when the material within the car will force the left side'door members 0 and d outwardl as shown in dotted lines in Fig. 1, and ful ines in Fig. 2, and in this operation the corresponding lever f and spring aid in forcing mental bottom members h may however, both be in the downwardly and outwardly inclined position, as shown at the left of Fig. 2, in ful lines, and at the right in dotted lines, when the car is filled and in this position the material therein may be dumped from both sides of'the car, as will be readily understood. The inner false or supplemental bottom members 71 are raised into the highest position, when desired by bars or similar devices inserted into the sockets or recesses g in the drums g and the said members h are held in their raised positions by the awls g opera-ting in connection with the rate ets g. It will also be understood that the door members 0 and d are held in their closed position by the pawls and (1 operating in connection with the ratchets c and d, and in order to release said door members, the pawls c and (i -must be raised, and the door members 0 and d are swung into the closedposition as shown in full lines in Fig; 1, by turning the drums .e and (i said operation being accomplished by cranks applied to the shafts m, of said drums or in any other desired manner.

If both of the inner or sup lemental bot tom members h are in their owest position when the car is filled, the entire contents may be dumped at one side of the car by opening the doors on said side and letting part of the load 'roll out, 'after which the inner false or supplemental bottom member h on the 0p osite side may beraised and the balance of t e contents of the car dumped as will be readily understood.

In the movement of the inner false or sup- Elemental bottom members h when the doors and c are closed, the slides i bear on said doors at all times and the space between the parts It and doors is securely closed.

Havin fully described my invention, what I'cfaim as new' and desire to secure by Letters Patent, 'is;-

'1. A dumping car provide d wan hinged side doors and inner supplemental bottom members which range lon itudinally of the car and are hinged centrally and longitudinally thereof said bottom members being provided with slides which are adapted to press against the doors and means for raising and lowering said bottom members and for closin and opening the doors. 1
